Isochoric process

Let us next return to the isochoric process which is represented by the figure below.



We already saw that while the ideal gas under a piston which is fixed and cannot move was heated, it did not produce work. The total heat required for such process is only needed for the increase of the total kinetic energy. Consequently, we have

Q_1→2 = E_kin(1→2) = 3ΔP V/2 = 3(P₂-P₁)V/2
